[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0023] This application proposes an FPC structure with built-in light sensing function. Figure 1 and Figure 2 , including: FPC10, control button 11, light-sensing IC12 and control button wiring structure 13. FPC10 includes a welding surface and an opposite surface opposite to the welding surface, and the control button 11 and the light-sensing IC12 are welded on the welding surface of FPC10. The control button wiring structure 13 is electrically connected to the control button 11 and the light-sensing IC12 respectively. FPC10 is provided with a through hole at the light-sensing IC12, and the external ambient light can be captured by the light-sensing IC12 through the through hole, so that the whole machine equipped with the FPC structure with built-in light-sensing function can sense the ambient light, and the light-sensing IC12 can also adjust the brightness of the control button 11 light and automatically adjust the screen brightness. The whole machine does not need to make a separate light-sensing accessory, and the touch button and light-sensing control function are integrated into one, making the whole machine structure more compact, saving space, and facilitating the integration of other functional accessories into the whole machine.

[0024] In one embodiment, the FPC structure with built-in light sensing function also includes a touch IC, which can realize the touch function. When the user operates on the touch surface of the display module, the operation instruction will be transmitted to the touch IC in the FPC10 through the wiring. The touch IC is electrically connected to the mainboard of the display module and further transmits the instruction to the mainboard for execution. For details, please refer to Figure 1 A component area 20 is provided on the welding surface of the FPC 10, and the touch IC is welded on the component area 20. Furthermore, the FPC structure with a self-contained light sensing function also includes a steel plate 21, which is provided on the opposite side of the FPC 10 to the component area 20, and reinforces the soft FPC 10 to support the component area 20 from bending or breaking. The steel plate 21 provides support for the component area 20 and enhances the hardness of the component area 20.

[0025] See also Figure 1 One end of the FPC 10 is provided with an insertion interface 22, which can quickly connect the FPC 10 to other components to improve efficiency. Furthermore, the FPC structure with built-in light sensing function also includes a PI reinforcement board 23, which is arranged on the opposite side of the insertion interface 22 on the FPC 10. The PI reinforcement board 23 has a high hardness and can reinforce the soft FPC 10 at the insertion interface 22, thereby improving the stability of the FPC 10 plug-in.

[0026] Among them, see Figure 1 There are five control buttons 11, which can control volume, adjust air conditioning wind size, play songs, etc. The FPC 10 is provided with patterns at the control buttons 11, so that the user can identify the control buttons 11 and operate the control buttons 11 accurately.

The horizontal plate and the vertical plate are both provided with a control button wiring structure 13 wiring structure, and the horizontal plate is provided with a component area 20. The horizontal plate and the vertical plate can be bent to save the length of the FPC 10 in the whole machine, making the structure more compact.

[0028] In another embodiment, see Figure 2 The FPC structure with built-in light sensing function also includes double-sided adhesive 24. The opposite side of the welding surface of FPC10 is bonded to the double-sided adhesive 24, so that FPC10 can be bonded to the cover plate in the display module through the double-sided adhesive 24, thereby improving assembly efficiency. In addition, the double-sided adhesive 24 is bonded to the horizontal plate, so that the horizontal plate can be bonded to the cover plate, and the vertical plate can be bent up to make the internal structure more compact. In addition, the FPC structure with built-in light sensing function also includes a GND copper layer. The GND copper layer is arranged on the horizontal plate. The GND copper layer is connected to the ground wire, which can reduce the interference of external signals on FPC10 and guide the external signals into the ground. The GND copper layer is arranged at the edge of the control button 11 of FPC10 to prevent the GND copper layer from contacting and conducting with the control button 11 and affecting the operation of the control button 11.
